Abstract
1,199,427. Making chains; broaching; welding by pressure. BECKER-PRUNTE G.m.b.H. 1 Dec., 1967 [5 Dec., 1966], No. 54869/67. Headings B3A, B3L and B3R. A machine for welding a chain of connected links comprises means for simultaneously operating welding and flash-removing means which are arranged respectively at two separate stations along the feed path of the chain, and first and second means for positioning and gripping two links aligned with a first plane, respectively at welding and flash-removing positions with slack between these two links, welding taking place preferably at a position to one side of a second plane mutually perpendicular to and intersecting, along the axis of movement of the chain, the first plane. Operation.-The chain is fed in steps equal to the pitch, two passes being necessary. In the first pass links 2, 4, 6 &c. aligned in a horizontal plane are welded, and in the second pass links 3, 5 &c. are welded. In each pass the links not being welded are aligned (as shown) in a vertical plane. The link 4 which is to have weld flash removed is positioned and gripped at the flash-removing station by a gripper 22 having a shaped link-engaging portion 23 (Fig. 6, not shown) which engages the limb of the link opposite to that in which the weld was made. When this link is gripped, jaws 7, 8 which define a link-engaging pocket at the welding station, position and grip the link 2 to be welded, the welding position being lower than the flash-removing position so that the link 3 lies slack at an angle. The jaw 8, slidably movable towards jaw 7, causes the split limb of the link to be pinched before welding. In the welding position (Fig. 4) the link is contacted by removable fixed electrode tips 15, 16 and movable electrode tips 17, 18. As welding of link 2 proceeds, e.g. by flash-butt welding, the flash is removed from link 4 by two knives 40, 41, the welding control mechanism and flashremoving control mechanism being simultaneously operated from a central control. When welding and flash removal are completed a finger 51 lifts link 2 out of the welding position and the chain moves forward to present link 2 at the flash-removal station and link 6 at the welding station. Modifications of the positioning and gripping means of the flash-removing station are described (Figs. 12-14, not shown). Electrodes 17, 18 and knives 40, 41 may be operated by fluid cylinders.
